Turnstone Biologics is a clinical stage biotechnology company developing new medicines to treat and cure solid tumors by pioneering a differentiated approach with a clinically validated technology, tumor infiltrating lymphocyte (TIL) therapy. Turnstone’s innovative TIL therapy, which is designed to extend the efficacy of TILs to multiple solid tumor indications by selecting and manufacturing the most potent tumor-reactive T-cells (Selected TILs) for tumor eradication, represents the Company’s foundational therapeutic modality driving its cancer immunotherapy pipeline. The Company recently commenced two clinical trials in various solid tumor types with its lead Selected TIL therapy candidate, TIDAL-01, one of which is in collaboration with Moffitt Cancer Center. Turnstone is developing additional strategies to further potentiate the clinical benefit of Selected TILs, including use in combination with their novel viral immunotherapy.

At Turnstone, the science drives decision-making and our therapeutics are designed with the patient foremost in mind. We continue to build a world-class, high-performing company that embraces being a learning organization with a sense of urgency. Imagine coming to work every day where over-communication, transparency, teaching, listening, asking, thinking, working hard, and having fun are normal – actually, expected. Imagine having a coach, mentor, peers, and partners where candid feedback, self-improvement, risk taking, failing, learning from that failing, and succeeding thereafter are what we call ‘another day at Turnstone’. If you are a passionate person, and our science excites you – this opportunity may be for you.
